7 Be it known thatlI, OnAnLEs V. WILSON, of the city of Newark, in the county of Essex, and State of'N'ew Jersey, havemade an improvement on Making a Pot 01 Bath for the Heating of Steel for Forging or Tempering; and I do hereby declare the following to be a full and exnct description of the same, reference being herein had to the drawings that accompany this specification, and which makepnrt of'the same- Figure 1 being asection, 'and Figure 2 apore ective view of the bath.

The nature of my improvement consists in combining a wrought-iron interior with a cast-iron exterior in the construction of the pot or bath. I

It has been found'in practice that constant use of a cast-iron pot to hold the lead tends to such a porousness 'in the iron as to materially waste the lead, the more especially as it is very rare for cast iron to be free from air-holes. To obviate this I form a wrought-iron receiver for the lead, of= any desired thickness and size, as shown at b in the drawings, and have a cast-iron case, a, of the necessary form and thickness, combined therewith at the foundry, thus forming a. pot or bath that is more economical of the lead, and ivill last ionger than the casting alone.

What I claim as my improvement, and desire to secure by Letters Patent, is-

The pot or hath made of wrought and east iron, combined substantially in the manner and for the purpose hereinnbove specified.

CHARLES v. WILSON.
